Abstract (en)
[origin: WO2019206772A1] The invention relates to a composite pane (1) having an electrically switchable functional element (2), at least comprising a first pane (3), a second pane (4) and a thermoplastic intermediate layer (5) which connects the first pane (3) to the second pane (4), including a first laminating film (5.1) with a thickness of at least 0.3 mm and one or more second laminating films (5.2) with a thickness of max. 70 µm respectively, wherein: the first laminating film (5.1) is introduced substantially flat between the first pane (3) and the second pane (4); the second laminating films (5.2) are introduced exclusively in the region of the at least one functional element (2) with a protrusion x of at least 1 mm and they protrude over the outer edges of the functional element (2) by max. 10 mm; and the direct layer sequence in the region of an electrically switchable functional element (2) consists of the first pane (3), the second laminating film (5.2), the electrically switchable functional element (2), optionally a further second laminating film (5.2), the first laminating film (5.1) and the second pane (4).
